Khaos.AppLifecycle

Opinionated lifecycle manager for ASP.NET Core and generic host applications.

Features

  • Startup and shutdown flows that wrap the host lifecycle
  • Outcome-driven flow engine shared by startup, shutdown, and scheduled flows
  • Lightweight in-process scheduler with conditional flows and optional overlap guards
  • Async lifecycle events for visibility and telemetry
  • NuGet content files that scaffold AppLifecycle/* folders in consuming projects

Getting Started

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddApplicationLifecycleManager(options =>
{
    options.Startup.Flow("DefaultStartup")
        .BeginWith<WarmupServicesStep>()
        .EndFlow();

    options.Shutdown.Flow("DefaultShutdown")
        .BeginWith<FlushMetricsStep>()
        .EndFlow();

    options.Scheduled.Flow("HealthCheck")
        .OnSchedule<EvergreenTrigger>()
        .NoOverlap()
        .BeginWith<HealthProbeStep>()
        .EndFlow();
});

builder.Services.AddTransient<WarmupServicesStep>();
builder.Services.AddTransient<FlushMetricsStep>();
builder.Services.AddTransient<HealthProbeStep>();
builder.Services.AddTransient<EvergreenTrigger>();

var app = builder.Build();
app.UseApplicationLifecycleManager();
app.Run();

Implement steps by inheriting IFlowStep<TContext> (StartupContext, ShutdownContext, or ScheduledContext). Implement triggers by inheriting IScheduleTrigger and returning the desired delay between runs.
